CORNER-FASTENER FOR BEDSTEADS.

To all whom it may concern Be it known that 1, Oscar S. FosTnR, of Utica, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Corner-Fasteners for Bedsteads; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the reference-numerals marked thereon, which form part of this specification.

This invention has reference to the manufacture and construction of metallic bedsteads.

It is an object of the invent-ion to relieve the stock from which bedposts for metallic bedsteads are made, and certain other elements that assume a stress from coming into juxtaposition, whereby to prevent a disruption, both in the bedpost stock and the stressreceiving elements.

These and other objects will become apparent upon further reading of this case, and by reference to the accompanying sheets of drawings forming a part of this specification, and whereon- Figure 1 illustrates mainly in perpendicular section a practical embodiment of the invention. Fig. 2 depicts the same construction through a view illustrating a transverse, sectional view with dotted-in features. Fig. 3 is a horizontal sectional view of a construction, involving the same principle of invention in association with another form of stress-receiving device and dotted-in features. Fig. 4 is a horizontal sectional view of still another form of construction involving the same general principle in association with the same sort of a stress-receiving device as is illustrated in Fig. 3. Fig. 5 is an end view showing an entry to the fastening means.

Similar characters of reference indicate similar parts in the drawings.

The metal stock from which the posts f are usuall made may be of any suitable contour and dimension. An opening 5, is formed in the wall of this stock to receive a stud 6, that may be suitably associated with, or formed as a part of an element 7, which in the case of Figs. 1, 2, and 3, may be located on the interior of the stock. Adapted to be applied to the outside of the post, in the Specification of Letters Patent.

Serial No. 681,205.

present instance, is a plate 8, which, in the present case, may be provided with a recess 9, which is adapted to take over the portion 6, of the plate 7, and this plate may also be provided with a recess 10, which is adapted to accommodate a shoulder 11, formed upon or in connection with the body 12, of a bolt that passes through the plate 8, and into the part 7, into which it may be screw-threaded as at 13. This bolt is provided with the usual head 14;, and serves as a stress-receiving member to accommodate any suitable form of coupling that may be provided on the end of side rails for beds.

By reference to Fig. 3, it will be observed that a substitute for the stress-receiving member, disclosed in Figs. 1, and 2, there may be provided that form which is disclosed in Fig. 3, and which, in practice, is commonly known as a frencher. This element, is designated by the numeral 15, and is provided with a recess 16, adapted to take over a projected end 6, of an interiorly located block 7, and which passes through an opening 5, formed in the wall of the stock. The element 15, is provided with an opening 17, having a reduced neck 18, and this element 15, may be counter-bored as at 19, through a plane, substantially at rightangles, to the plane of the opening 21, so as to provide a seat 20, and through an opening 21, in the element 15, a bolt 22, is screwthreaded as at 23, into the member 7, so that the head 24, thereof may come against the base of said seat.

By reference to Fig. i, the general construction of the element 15, is the same, excepting that it is provided with an extension 6, that passes through an opening 5, in the wall of the stock, and occupies a recess 25, in a plate 7, situated in the inside of the stock. A bolt 22, having a head 24, passes through an opening 21, in the element 15, and is screw-threaded into the element 7 while the head 2%, rests against the seat 20, in the element 15.

By reference to the dotted-in formations 26, 27, and 28, at Figs. 2, 3, and l, it will be noted that this invention contemplates the provision of means in conjunction with any form of stress members for carrying the cross stays at the head and foot of the bed, and for carrying them in or out of alinement with the axis of the posts.

The main idea of the invention resides in relieving the stress-receiving element and the wall of the stock from supporting of other, which, by reason of the thinness of the stock would tend to disrupt the stock and the stress-receiving element. By clamping the stock between the two plates, through the instrumentality of the screw-threaded portions of the stress-receiving member and one of the elements, in conjunction with that portion extends through the opening in the stock, the wall of the opening is not only shielded against disruption, but the clamping of the inner and outer plates against the stock strengthens the latter, in its compacity as a bearing for the projected portion 6 of the clamping elements.

As before intimated, the illustrations on the drawing indicate some of the practical embodiments into which the inventive conception may be adopted. It follows, however, that within the range of invention variations, prompted by practice, may be resorted to without departure from the invention.

It will be noticed that the exterior element 7 has its surface toward the inner surface of the post L} shaped to fit thereagainst and that the surface of the exterior element 8 has its surface toward the post correspond ingly tted to the adjacent outer surface of the post, in order that the pressure of damp ing of the post between said two members may be evenly distributed over as large a surface as practicable.

Where as in the forms shown in Figs. 3 and a the part of the post so grasped is not flat, this shaping of the two elements, operates when the fastening is assembled to keep the elements in perpendicular aline ment with each other and with the post. This tends to prevent the fastening from becoming loosened and prevents its being assembled in such a position or being moved after being assembled, to such a position as would prevent the stress receiving element from readily receiving its complementary part upon the side rail. W'hee as in the dotted constructions shown in Figs. 2 and 4; the outer clamping element has a laterally extending projection as 26 or 28 to receive cross pieces of the head or foot, this close shaping of both elements is useful in that it distributes the turning pressure over the whole fastening devi e instead of forcing he clamping member to receive this strain. Where as in l and 2 the surface of the post receiving the fastener is flat, these results are obtained by having the interior element extend laterally on one or both sides to the adjacent angle of the post stock, and by having the exterior element provided with a flange 30 adapted to overlap one side edge of the post 4:.

It will be evident that the feature of having the outwardly extending end of the clamping bolt the stress-receiving member as in Figs. 1 and 2 may be combined with the modification illustrated in Fig. 4 of having the interior element receive the projection from the other or exterior element but the construction as in Figs. 1 to 3 of having the projection on the interior element re ceived in a seat in the exterior element is preferred as this arrangement provides greater depth for the screw threaded portion of the interior element with which the screw thread is associated.

Having thus described this invention, I claim 1. In a detachable corner fastener for bed steads the combination of a post having an opening therein, clamping elements adapt ed to be applied respectively to the inner and outer sides of the post adjacent to said opening, a projection on one of said clamping elements extending through said opening and fitting into a recess provided in the other clamping element, a bolt screw-threaded into the interior clamping elementand bearing against the exterior clamping element and adapted to force said clamping Zelements toward each other and against said post and stress receiving means carried by one of said exterior parts.

2. In a detachable corner fastener for bedsteads the combination of a post having an opening therein, clamping elements adapted to be applied respectively to the inner and outer sides of the post adjacent to said opening, a projection on one of said. clamping elements extending through said opening and fitting into a recess provided in the other clamping element, a bolt screwthreaded into the interior clamping element and inclosed within said projection and bearing against the exterior clamping element and adapted to force said clamping elements toward each other and against said post and stress receiving means carried by one of said exterior parts.

In witness whereof I have affixed my sig nature, in the presence of two witnesses, this 26th day of February 1912.
